Andrew Gregg, a resident of the township who had been a member of Congress from 1791 for sixteen years and United States Senator from 1807 to 1813. Its earliest settlers were George Woods in 1774, and George McCormick who settled at Spring Mills in 1773 and built the first mill there. It is a rich agricultural township.
